 *
 *	Abstract:
 *		This is the implementation file for the Conference Roster Class.
 *		Instances of this class represent a single Conference Roster's
 *		information base.  It encapsulates all the functionality required to
 *		maintain the information base which includes the ability to add new
 *		roster records, delete records and update records.  It has the ability
 *		to convert its internal information base into a list of conference
 *		records that can be used in a GCC_ROSTER_UPDATE_INDICATION callback.
 *		It is also responsible for converting its internal information base
 *		into Conference Roster Update PDUs.  Basically,  this class is
 *		responsible for all operations that require direct access to the
 *		records contained in a Conference Roster.
 *
 *		The Conference Roster class incorporates Rogue Wave list to hold the
 *		roster record information.  Using iterators throughout the class makes
 *		it easy to quickly convert the information contained in the list into
 *		either a PDU or into a list of record pointers (for roster update
 *		indications back to the node controller).
 *
 *		A Conference Roster object has the ability to serialize its roster data
 *		into a single contiguous memory block when it is required to send a
 *		message to the application interface.  This serialization process is
 *		managed externally by the CConfRosterMsg class through calls
 *		to LockConferenceRoster(), UnLockConferenceRoster() and
 *		GetConfRoster().  When a conference roster is to be serialized, a
 *		call is made to LockConferenceRoster() which causes the CConfRoster
 *		object to increment an internal lock count and returns the number of
 *		bytes required to hold the complete roster update.  The Conference
 *		Roster is then serialized into memory through a call to
 *		GetConfRoster().  The CConfRoster is then unlocked to allow
 *		it to be deleted when the free flag gets set through the
 *		FreeConferenceRoster() function.  In the current implementation of GCC,
 *		FreeConferenceRoster() is not used since the CConfRosterMsg
 *		maintains the data used to deliver the message.
 *
 *	Private Instance Variables:
 *		m_RecordList2
 *			This is the rogue wave list used to hold the pointers to all of the
 *			rogue wave records.
 *		m_nInstanceNumber
 *			This instance variable maintains an up to date instance #
 *			corresponding to the current conference roster.
 *		m_fNodesAdded
 *			Flag indicating if any node records have been added to the
 *			conference roster since the last reset.
 *		m_fNodesRemoved
 *			Flag indicating if any node records have been removed from the
 *			conference roster since the last reset.
 *		m_fRosterChanged
 *			Flag indicating if the roster has changed since the last reset.
 *		m_uidTopProvider
 *			The node id of the top provider in the conference.
 *		m_uidSuperiorNode
 *			This is the node id of this nodes superior node.  For the top
 *			provider this is zero.
 *		m_cbDataMemorySize
 *			This is the number of bytes required to hold the data associated
 *			with a roster update message.  This is calculated on a lock.
 *		m_NodeInformation		
 *			Structure used to hold the roster update indication node information
 *			data in "PDU" form.
 *		m_fTopProvider
 *			Flag indicating if the node where this roster lives is the top
 *			provider.
 *		m_fLocalRoster
 *			Flag indicating if the roster data is associated with a local
 *			roster (maintaining intermediate node data) or global roster (
 *			(maintaining roster data for the whole conference).
 *		m_fMaintainPduBuffer
 *			Flag indicating if it is necessary for this roster object to
 *			maintain internal PDU data.  Won't be necessary for global rosters
 *			at subordinate nodes.
 *		m_fPduFlushed
 *			Flag indicating if the PDU that currently exists has been flushed.
 *		m_pNodeRecordUpdateSet
 *			Pointer to internal PDU data.
 *
 *	Caveats:
 *		None.
